Wasabi v3 no longer takes disks

Hello, great forum here. So I installed the wasabi v3 on a d2e wii, 9 soldered wires. It worked great for about a week,took and read backup disks, now the drive will not take disks at all, it's like its dead. I unplugged the wii and restarted it, no luck. I noticed some users are talking about the K? point so you can reset the wasabi? Do you think I have to do this? Any help would be appreciated. If so could you point me to a picture of the K point soldered?

Interesting, my wii is in my entertainment center so it's not ever moved. Last night I unplugged the wii and this morning I plugged it in, once it powered up the drive is accessed????????? It's working again. I'm going to see for the cold solder joint, sounds like that might be the problem????
